>From IGNITE-8571: Now we have only one way to change BLAT - manually update it via console.sh or API. We need to add the possibility to change it automatically. Adjust to current topology. So, I propose 3 new parameters which would be responsible to tune this feature. 1. Flag autoAdjustEnabled - true/false. Easy. Manual baseline control or auto adjusting baseline. 2. autoAdjustTimeout - time which we would wait after the actual topology change. But it would be reset if new discovery event happened. (node join/exit). 3. autoAdjustMaxTimeout - time which we would wait from the first dicovery event in the chain. If we achieved it than we would change BLAT right away (no matter were another node join/exit happened or not). We need to change API next way: 1. org.apache.ignite.IgniteCluster *Add* isBaselineAutoAdjustEnabled() setBaselineAutoAdjustEnabled(boolean enabled); setBaselineAutoAdjustTimeout(long timeoutInMs); setBaselineAutoAdjustMaxTimeout(long timeoutInMs); 2. org.apache.ignite.configuration.IgniteConfiguration *Add* IgniteConfiguration setBaselineAutoAdjustEnabled(boolean enabled); IgniteConfiguration setBaselineAutoAdjustTimeout(long timeoutInMs); IgniteConfiguration setBaselineAutoAdjustMaxTimeout(long timeoutInMs); Also, we need to ensure that all nodes would have the same parameters. And we should be able to survive coordinator left during parameters changes. - For IGNITE-8575: Proposed API format for control.sh: {{--baseline autoadjust disable}} {{--baseline autoadjust enable <softTimeout> <hardTimeout>}} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
